TORONTO — A cash-strapped roofer who owed the Chinese mafia $30,000 over a drug debt testified Wednesday that he agreed to kill rich philanthropist Glen Davis for $150,000 in December 2005.

Tyler Cawley stated that Dmitri Kossyrine gave him $46,000 in one envelope and a photo of his murder target, Davis, plus maps pinpointing his home and office in another envelope.

Cawley, now 30, worked for a roofing contractor, who was hired by Kossyrine at various job sites in Toronto where Cawley worked alongside “Eugene” Vorobiov.

Cawley said he spent the deposit on “drugs, strippers, that kind of thing and the $30,000 I owed to the Chinese.”

Kossyrine, 34, has pleaded not guilty to first-degree murder in the May 18, 2007, shooting of Davis, 66, in a midtown Toronto parking lot.

Vorobiov is the alleged shooter while Kossyrine is the alleged middleman.

The execution of Davis was orchestrated by his relative Marshall Ross, who was drowning in debts owed to Davis, court heard earlier.

Kossyrine is also alleged to be the middleman who hired Cawley for the first, failed assassination bid in December 2005.

After handing Cawley the two envelopes, Kossyrine drove Cawley to Davis’ office and his home.

Cawley, who as addicted to crack, cocaine and oxycontin at the time, said he recalled his chats with Kossyrine took place in December 2005 because they were working on a massive Bridle Path mansion’s garage at that time.

On the day of the murder bid, Cawley drove his older, taller and thinner cousin to ambush Davis with a baseball bat outside his office. The witness and his cousin parked their minivan behind a row of bushes until Davis arrived at work and then the cousin leaped out the van, through the bushes and attacked the unsuspecting Davis.

“I heard screams, the word, ‘Hey,’ and not a second later, my cousin came running around and jumped into our vehicle and we took off,” testified Cawley.

“I thought Glen Davis was dead because that’s what my cousin was supposed to do,” said Cawley.
